calcule os produtos nos radicais

me ajudem!!!​

Answer 1

a) = 2√6

b) = 3√2

$\Large{\sf{\Huge ————————————————}}$

$\large\gray{\sqrt{8} \times \sqrt{3} = \sqrt{24}}$

simplificando:

$\qquad\boxed{ \begin{array}{l}\qquad\sf\large \green{ \sqrt{24} } \blue{ } \red{ } \green{ } \pink{ } \purple{ } \qquad \qquad \\ \\ \qquad \sf\large \orange{ \sqrt{4\times 6}} \pink{ } \blue{ } \red{ } \green{ } \pink{ } \purple{ } \\ \\ \qquad \large \sf \purple{\sqrt{2^{2}} \times \sqrt{6} } \green{ } \blue{ } \red{ } \green{ } \pink{ } \purple{ } \\ \\ \qquad \sf\large \red{ \sqrt{2^{2}}} \green{\times } \blue{ } \red{ } \green{ } \pink{ } \purple{ \sqrt{6} } \\ \\ \qquad \large \sf \blue{ 2 \sqrt{6} } \green{ } \blue{ } \red{ } \green{ } \pink{ } \purple{ } \end{array}}$

$\sf\large\gray{\sqrt{3} \times \sqrt{6} = \sqrt{18}}$

simplificando:

$\qquad\boxed{ \begin{array}{l}\qquad\sf\large \blue{ \sqrt{18} } \blue{ } \red{ } \green{ } \pink{ } \purple{ } \qquad \qquad \\ \\ \qquad \sf\large \red{ \sqrt{9\times 2}} \green{ } \blue{ } \red{ } \green{ } \pink{ } \purple{ } \\ \\ \qquad \large \sf \green{ \sqrt{3^{2}} \times \sqrt{2} } \green{ } \blue{ } \red{ } \green{ } \pink{ } \purple{ } \\ \\ \qquad \sf\large \pink{ \sqrt{3^{2}}} \green{\times } \blue{ } \red{ } \green{ } \pink{ } \purple{ \sqrt{2} } \\ \\ \qquad \large \sf \blue{ 3 \sqrt{2} } \green{ } \blue{ } \red{ } \green{ } \pink{ } \purple{ } \end{array}}$

Answer 2

Resposta:

$a)3 \sqrt{6} \\ ou \: na \: forma \: alternativa \: e \\ 4.89898$

$b)3 \sqrt{2} \\ ou \: na \:forma \: alternativa \: e. \\4.24264$

Explicação passo-a-passo:

$a) \sqrt{8} \sqrt{3} \\ \sqrt{8} \sqrt{3} \\ \sqrt{8 \times 3} \\ \sqrt{24} \\ \sqrt{8} \sqrt{3} \\ \sqrt{24} \\ \sqrt{4 \times 6} \\ \sqrt{2 {}^{2} \times 6} \\ \sqrt{2 {}^{2}} \sqrt{6}\\2 \sqrt{6} \\ resposta \\ 2 \sqrt{6} \\ b) \sqrt{3} \sqrt{6} \\ \sqrt{3} \sqrt{6} \\ \sqrt{3 \times 6} \\ \sqrt{18} \\ \sqrt{3} \sqrt{6} \\ \sqrt{18} \\ \sqrt{9 \times 2} \\ \sqrt{3 {}^{2} \times 2} \\ \sqrt{3 {}^{2}} \sqrt{2} \\ 3 \sqrt{2} \\ \sqrt{18} \\ 3 \sqrt{2} \\ resposta \\ 3 \sqrt{2}$
